摘要： A building system for seismic-active areas includes a base structure and an upper structure connected to the base structure by a system of connector means which collectively provide a relatively rigid interconnection under normal conditions and a relatively flexible connection when subjected to seismic disturbances. When the building system is subjected to seismic disturbances, rigid connector members fail by buckling and other connector members flex without failing to provide the relatively flexible interconnection.

摘要： A gravity base offshore production platform structure and, more particularly, a production platform for use in an arctic environment, including an encircling structure having a predetermined configuration the protection of the offshore structure in iceberg-infested waters which are capable of resisting the destructive forces of an impact produced by a large iceberg. The gravity base offshore production platform structure consists of a monolithic, massive concrete structure of a configuration providing a plurality or horizontal array of upright, mostly cylindrical compartments, which is supported on a concrete or slab foundation nesting on the marine floor. Generally, although not necessarily, the compartmented structure rises above the marine surface and is covered by a concrete slab or similar covering structure to thereby form closed compartments within the monolithic structure. The circumference of the concrete structure incorporates a plurality of ice-deflecting nose portions which are integrally formed with the wall structure of the exteriorly located compartments of the array, and are reinforced to withstand large iceberg forces upon impact. These reinforced nose portions impart either a "scallop-like" configuration to the circumference of the structure, or when in the shape of substantially pointed wall sections, a "starpoint" form capable of resisting and absorbing extremely high energy of large, fast moving and strong icebergs by progressively crushing the leading edge of an impacting iceberg.

摘要： A T-headed stirrup for anchoring reinforcing bars in concrete, to restrain lateral buckling of the reinforcing bars under severe forces. The stirrup, comprising a shaft with a T-shaped crosspiece at each end, is typically inserted between pairs of reinforcing bars. The crosspiece contacts the reinforcing bar and is shaped to restrain lateral movement of the reinforcing bar.

摘要： A structure for use in exploiting arctic offshore areas where floating ice masses may be present. The structure is comprised of a floating hull having ice-breaking capabilities which is moored by a plurality of mooring means which extend vertically from a moonpool in the hull to the marine bottom directly under the hull. The mooring means comprises flexible lines, e.g. nylon, steel, or the like or rigid conduits, e.g. drill pipe.Means are provided within the moonpool for tensioning the mooring means to thereby draw the hull downward to a position below its normal buoyant position thereby substantially eliminating vertical heaving of the hull. When an ice mass contacts the hull, tension on the mooring means is relaxed to thereby allow the hull to rock upward against the ice thereby generating the forces necessary for the ice-breaking operation. Due to the present mooring means, the hull moves only a relatively short lateral distance in breaking an approaching ice mass. This is important in floating drilling operations.Further, if repair or replacement of a mooring means is required, this can be accomplished even when ice surrounds the hull since the mooring means are anchored directly below the hull and are easily accessible through the moonpool.
摘要翻译：用于开发可能存在浮冰块的北极近海地区的结构。该结构由具有防破坏能力的浮体组成，其由多个系泊装置系泊，该系泊装置从船体中的月球垂直延伸到船体正下方的海底。系泊装置包括柔性线，例如。尼龙，钢或类似物或刚性导管，例如。钻杆。在月球中设置有用于张紧系泊装置的装置，从而将船体向下拉到低于其正常浮力位置的位置，从而基本上消除了船体的垂直沉降。当冰体接触船体时，系泊装置上的张力被松弛，从而允许船体向上抵靠冰面向上摇晃，从而产生破冰作用所需的力。由于目前的系泊装置，船体在打开接近的冰块时仅移动较短的横向距离。这对浮动钻井作业很重要。此外，如果需要修理或更换系泊装置，即使在围绕船体的情况下也可以实现这一点，因为系泊装置直接锚固在船体的下方并且容易通过月球接近。
